2018-12-18mac80211: remove superfluous NULL checkJohannes Berg1-1/+1
At the place where this code lives now, the skb can never be NULL, so we can remove the pointless NULL check. It seems to exist because this code was moved around a few times and originally came from a place where it could in fact be NULL. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2018-12-18mac80211: never pass NULL params to ieee80211_if_add()Johannes Berg2-7/+7
This isn't really a problem now, but it means that the function has a few NULL checks that are only relevant when coming from the initial interface added in mac80211, and that's confusing. Just pass non-NULL (but equivalently empty) in that case and remove all the NULL checks.

2018-12-18mac80211: Properly handle SKB with radiotap onlyIlan Peer1-9/+17
The monitor interface Rx handling of SKBs that contain only radiotap information was buggy as it tried to access the SKB assuming it contains a frame. To fix this, check the RX_FLAG_NO_PSDU flag in the Rx status (indicting that the SKB contains only radiotap information), and do not perform data path specific processing when the flag is set.

2018-12-18mac80211: fix a kernel panic when TXing after TXQ teardownSara Sharon2-2/+3
Recently TXQ teardown was moved earlier in ieee80211_unregister_hw(), to avoid a use-after-free of the netdev data. However, interfaces aren't fully removed at the point, and cfg80211_shutdown_all_interfaces can for example, TX a deauth frame. Move the TXQ teardown to the point between cfg80211_shutdown_all_interfaces and the free of netdev queues, so we can be sure they are torn down before netdev is freed, but after there is no ongoing TX.

2018-12-18nfp: flower: fix cb_ident duplicate in indirect block registerJohn Hurley1-10/+11
Previously the identifier used for indirect block callback registry and for block rule cb registry (when done via indirect blocks) was the pointer to the netdev we were interested in receiving updates on. This worked fine if a single app existed that registered one callback per netdev of interest. However, if multiple cards are in place and, in turn, multiple apps, then each app may register the same callback with the same identifier to both the netdev's indirect block cb list and to a block's cb list. This can lead to EEXIST errors and/or incorrect cb deletions. Prevent this conflict by using the app pointer as the identifier for netdev indirect block cb registry, allowing each app to register a unique callback per netdev. For block cb registry, the same app may register multiple cbs to the same block if using TC shared blocks. Instead of the app, use the pointer to the allocated cb_priv data as the identifier here. This means that there can be a unique block callback for each app/netdev combo.

2018-12-18net: dccp: initialize (addr,port) listening hashtablePeter Oskolkov2-0/+4
Commit d9fbc7f6431f "net: tcp: prefer listeners bound to an address" removes port-only listener lookups. This caused segfaults in DCCP lookups because DCCP did not initialize the (addr,port) hashtable. This patch adds said initialization. The only non-trivial issue here is the size of the new hashtable. It seemed reasonable to make it match the size of the port-only hashtable (= INET_LHTABLE_SIZE) that was used previously. Other parameters to inet_hashinfo2_init() match those used in TCP. V2 changes: marked inet_hashinfo2_init as an exported symbol so that DCCP compiles when configured as a module. Tested: syzcaller issues fixed; the second patch in the patchset tests that DCCP lookups work correctly.

2018-12-18bnxt_en: Disable MSIX before re-reserving NQs/CMPL rings.Michael Chan1-8/+11
When bringing up a device, the code checks to see if the number of MSIX has changed. pci_disable_msix() should be called first before changing the number of reserved NQs/CMPL rings. This ensures that the MSIX vectors associated with the NQs/CMPL rings are still properly mapped when pci_disable_msix() masks the vectors. This patch will prevent errors when RDMA support is added for the new 57500 chips. When the RDMA driver shuts down, the number of NQs is decreased and we must use the new sequence to prevent MSIX errors.

Also add a new parameter resv_stat_ctxs to better keep track of stat_ctxs reserved including resources used by RDMA. Add a stat_ctxs parameter to all the relevant resource reservation functions so we can reserve the correct number of stat_ctxs.

2018-12-18fou: Prevent unbounded recursion in GUE error handlerStefano Brivio1-0/+7
Handling exceptions for direct UDP encapsulation in GUE (that is, UDP-in-UDP) leads to unbounded recursion in the GUE exception handler, syzbot reported. While draft-ietf-intarea-gue-06 doesn't explicitly forbid direct encapsulation of UDP in GUE, it probably doesn't make sense to set up GUE this way, and it's currently not even possible to configure this. Skip exception handling if the GUE proto/ctype field is set to the UDP protocol number. Should we need to handle exceptions for UDP-in-GUE one day, we might need to either explicitly set a bound for recursion, or implement a special iterative handling for these cases.

2018-12-18security: don't use a negative Opt_err token indexLinus Torvalds2-2/+2
The code uses a bitmap to check for duplicate tokens during parsing, and that doesn't work at all for the negative Opt_err token case. There is absolutely no reason to make Opt_err be negative, and in fact it only confuses things, since some of the affected functions actually return a positive Opt_xyz enum _or_ a regular negative error code (eg -EINVAL), and using -1 for Opt_err makes no sense. There are similar problems in ima_policy.c and key encryption, but they don't have the immediate bug wrt bitmap handing, and ima_policy.c in particular needs a different patch to make the enum values match the token array index. Mimi is sending that separately.

2018-12-17net/mlx5e: Use dedicated uplink vport netdev representorOr Gerlitz8-121/+212
Currently, when running in sriov switchdev mode, we are using the PF netdevice as the uplink representor, this is problematic from few aspects: - will break when the PF isn't eswitch manager (e.g smart NIC env) - misalignment with other NIC switchdev drivers - makes us have and maintain special code, hurts the driver quality/robustness - which in turn opens the door for future bugs As of each and all of the above, we move to have a dedicated netdev representor for the uplink vport in a similar manner done for for the VF vports. This includes the following: 1. have an uplink rep netdev as we have for VF reps 2. all reps use same load/unload functions 3. HW stats for uplink based on physical port counters and not vport counters 4. link state for the uplink managed through PAOS and not vport state 5. the uplink rep has sysfs link to the PF PCI function && uses the PF MAC address Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
